Condom

ABSTRACT

A condom which can be fitted onto a penis without requiring for fingers to touch the penis and a condom body when in use, and which preferably does not admit the entry of air during fitting and is free from remnant air after fitting, wherein extension portions ( 5 ) of a specified length are ensured on a fitting tape (B) rolled up along with the condom body (A), and the condom body can be stored in a package (C) without this length being increased nor decreased during a packaging process.

TECHNICAL FIELD

This invention relates to a condom, and more specifically, to a condomwhich can be fitted without the fingers touching the penis or the condombody, to a condom which is easy to fit and air does not enter when thecondom is to be fitted, and to a condom wherein air does not enter orremain in a sperm retention part or the vicinity of the glans part.

BACKGROUND ART

According to the prior art, condoms are fitted by breaking the seal of apackage, removing the condom body and fitting it on the penis with thefingers, but as the fingers touch the penis and the condom body when itis fitted, there is a problem as to hygiene and whether the condom fitssatisfactorily, and if any lubricating oil or powder is used, it adheresto the fingers and must therefore be wiped off. Further, as air entersthe condom body, the air must be expelled when it is fitted, which was anuisance.

A method has been proposed wherein the condom body is provided with afitting tape having grip parts which is rolled up together with thecondom, and when the condom is to be fitted, these grip parts arepulled, e.g., as disclosed in Japanese Patent Publication Hei 2-33765,Japanese Patents Laid-Open Hei 8-56978 and Japanese Utility and DesignPatent 3029333. However, the condom body cannot be fitted withoutremoving from its package, so it must again be touched with the fingers.

In another type of condom fitted without removing it from its packagewith the fingers, and without touching the penis or condom body with thefingers while it is still in its package, a fitting tape is rolled uptogether with the condom, an extension part is formed beyond this rolledpart, and the tip of this part is sealed to the rim of the package, asdisclosed in, e.g., Japanese Patent Laid-Open Sho 63-195823, JapanesePatent Publication Hei 3-505173, Japanese Patent Publication Hei10-510452 and Japanese Patent Laid-Open Hei 11-19110.

However, although these proposals (creative ideas) describe how to fitthe condom without touching it with the fingers, it is difficult inpractice to fit the condom without touching it. Further, there are alarge number of parts and steps involved, the construction is complexand manufacture is difficult. Stability and reliability of steps couldnot be expected, no consideration was given to maintaining the length ofthe extension part formed at the tip of the rolled part at apredetermined length, and the condom body unrolled when the package wasopened. Due to these manufacturing problems, the product was notcommercialized.

If the extension part is short, the fitting tape is pulled and therolled part is also pulled out when the package is opened, so the condombody is unrolled too much, and if it is fitted in this state, airremains in the glans part. On the other hand, if the extension part islong, although the condom body does not unroll too much when the packageis opened, the fitting tape is pulled out too long after opening thepackage, and the condom body droops down when it is fitted. Hence, itwas not easy to fix it on the glans, the fitting stroke was too long,and the user's thigh and hand interfered with each other which madefitting difficult.

The problem common to all these ideas was that, as the tip of theextension part and the rim of the package were sealed simultaneously,the expected length of the extension part easily tended to increase ordecrease. Due to the construction of the product, in the steps leadingto the final step of the packaging, this could not be resolved andmanufacture of the condom was therefore difficult. Moreover in theseproposals, no consideration whatever was given to maintaining the lengthof the extension part within a predetermined range, or to means toachieving that end.

In these condom bodies, there is a sperm retention area in the glanspart. Air entered the sperm retention area when the package was openedor the condom was fitted, and remained after the condom was fitted.

There have been proposals for designs which expel the air in the spermretention part, but in practice, there was still a risk that air wouldenter when the condom was fitted.

As there is a sperm retention area in the glans part, a considerableamount of air is trapped when the package is opened and the condom bodyis fitted, and it was difficult to expel this air completely. Due tothis accumulation of air, the rubber film of the condom body does notfit closely around the glans, various fatal problems tended to occursuch as loss of sexual sensation, a tendency to rupture of the condombody or the condom body easily falling off the penis. To expel theretained air, it was necessary to touch the condom body or the peniswith the fingers which gave rise to the above problems or difficultiesof usage.

To open the package, it must be split into two equal parts, and as it isgenerally difficult to split it precisely into two parts, the idea wasconceived of providing a seam approximately in the center of the frontand rear surfaces. However, it is difficult to make the starting andfinishing points of the seam coincide precisely on both the front andrear surfaces during packaging and sealing.

It is therefore an object of this invention to provide a condom whereinan extension part of predetermined length is provided in a fitting tapewhich is rolled up together with the condom body, i.e., beyond therolled part. The tip of the extension part is fixed to a predeterminedposition of the packaging before the package rim is sealed in one pieceso that its length does not fluctuate in the packaging step. The packagematerial of the rim of the condom body is then sealed. The condom bodycan suitably be fixed on the glans without directly touching the penisor condom body, and without unrolling the condom body more thannecessary when the package is opened. Hence the condom can be fittedwithout touching, and furthermore, air does not enter between the glansand the condom when the condom is fitted.

DISCLOSURE OF THE INVENTION

According to this invention, when the condom body is rolled up, a pairof fitting tapes are laterally disposed to the left and right of thecondom body. One end of these fitting tapes is disposed in the vicinityof the opening of the condom, the tapes are rolled up together with thecondom body along its opposite lateral surfaces, and extension parts arerespectively provided in the vicinity of the glans beyond the rolledpart of the fitting tapes. After the tips of the extension parts aresealed in one piece with the inner surface of one of the upper packagematerial and lower package material of the package, the other packagematerial is placed over the condom body, and the rims of the packagematerials are sealed at positions slightly removed from the rim of thecondom so as to enclose the condom body. In this way, the extensionparts can be maintained at a predetermined length in a step wherein therolled condom body is made into a sandwich shape by the upper and lowerpackage materials, or in an immediately following step wherein the rimof the condom body is thermocompression bonded.

The seal part between the extension part of the fitting tape and theupper package material is set at about ⅔ of the radius fromapproximately the outer circumference of the condom body towards thecenter of the condom. Hence, the length of the extension part isrationally determined within the optimum range from the viewpoint ofmanufacturing technique, and can be set to the most preferable length.

This resolves the defects inherent in having the extension part of thefitting tape too short, and the disadvantages and difficulties involvedin having the extension part too long. As a result, the condom can besuitably fixed on the glans without directly touching the penis or thecondom body with the fingers, i.e., a “no touch” fitting is possible.

It is preferred that the glans part of the condom body is fashioned inthe shape of a close-cropped monk's head. As there is no sperm retentionarea in the glans part, there is no risk that air will enter the condombody when it is fitted, and no concern that air will remain. Therefore,the condom is free from the aforesaid problems and disadvantagesassociated with entry of air.

According to this invention, before sealing the tip of the fitting tapeto the package rim in one piece, the extension part is sealed to theupper package material or lower package material of the package. Hence,the extension part need not be eliminated, the shape of the extensionpart can be maintained, and it can be firmly sealed to the package rimwithout the tip (excess length) of the fitting tape biting. This alsoprevents rolling back of excess condom body due to temporaryinterruptions in pulling the fitting tape, or to sudden pulling under aload.

According to this invention, a notch for opening the package is providedsubstantially in the center of the upper end, and plural rows of tearlines are provided in the package opening direction substantially in thecenter of the upper package material or lower package material, or inboth, along the notch. As a result, the roughness of the package rimdisappears, opening the package is easier, and as tear lines coincidewith other parallel tear lines, even if the positioning of a tear lineis slightly to the left or right of the predetermined position in thepackage forming step, smooth opening of the package is enhanced.

BEST MODES FOR CARRYING OUT THE INVENTION

This invention will now be described in further detail with reference tothe drawings.

A condom according to this invention basically comprises a condom bodyA, a pair of fitting tapes B to the left and right, and a package C.Before a rim c of the package C is sealed 9 by thermocompressionbonding, the fitting tape B is sealed 3 to the inner surface of an upperpackage material 1 or lower package material 2, and the rim c of thepackage C is then sealed 9 so as to enclose the condom body A.

The condom body A of this invention is formed as an ordinary thin filmcylindrical envelope of latex rubber or synthetic resin known in the artin this kind of technical field. There is no restriction on its shape,i.e., there may be a sperm retention area in a glans part a or it may beshaped as a monk's head without a sperm retention part. The monk's headshape is preferred to prevent entry or retention of air, the tip ispreferably formed in a flat, curved shape, and a coil is formed in theopening. The coiled width (diameter) is preferably the same as thestandard width for products in common use, or a larger diameter than thestandard width for products in common use. The pair of fitting tapes Bon the left and right are wound together along the opposite lateralsurfaces of the condom body A, and these tapes B are housed in thepackage C such that they are somewhat coiled by winding.

According to this invention, the coiled width (diameter) of the condombody A is preferably effectively equal to that of the standard diameterof products in common use, or a larger diameter than the standard widthfor products in common use. By making the width a large width ofapproximately 53-59 mm (diameter approximately 34-38 mm) in comparisonto the coiled width of products in common use, which is approximately51-52 mm (diameter approximately 32-33 mm), idle rotation of the condomon the glans when the condom is fitted is prevented.

Hence, when the diameter of the condom body A is formed larger than thestandard diameter common products, the condom can be fitted smoothlywithout idle rotation on the glans when it is fitted as describedhereabove, it fits easier on the glans by making the glans part a flat,and fitting by the fitting tapes B is made still easier.

The flat, curved shape of the tip refers to the relation between theradius of the condom body A and the diameter of the apex of the glanspart a, where a flat shape resembling that of a crushed hemisphere ispreferable.

The fitting tapes B are tapes of suitable width comprising any flexible,pliable material such as paper or plastic which can be rolled togetherwith the condom body along the opposite lateral faces of the condom bodyA, e.g., a pair of low density left/right polyethylene tapes of widthapproximately 10 mm. One end of each of the fitting tapes B is situatedin the vicinity of the opening of the condom body A, and the other endsare situated to the left and right along the outer surfaces of thecondom so that they can be extended towards the glans part of thecondom, and rolled up together with the condom body A. Extension parts 5are formed in the left and right fitting tapes B beyond a coiled part 4,i.e., in the vicinity of the glans part a, and the tips of the splitextension parts 5 are sealed 3 in one piece with the inner surface ofone of the upper package 1 or lower package 2 prior to sealing the rim cof the package C by thermocompression bonding or the like.

The position of this seal part 3 may be situated more towards the inside(FIG. 2) or outside (FIG. 6) than the outer circumference of the rolledup condom body A, and although it is not the only possible arrangement,the length of the extension part 5 is determined by this seal 3.

After opening the package C, the condom body A is unrolled and fitted bypulling package pieces C′ to the left and right of the part where thepair of left and right fitting tapes B used in this invention are sealed(3), downwards. It is therefore indispensable to form the extensionparts 5 in a predetermined length in the left and right fitting tapes Bso the condom body A does not roll out when the package is opened, andthe condom body A does not droop after the package is opened. Therefore,the length of the extension parts 5 is set in a predetermined range, andthey are provided equally to the left and right on the front surface orthe rolled rear surface in the vicinity of the glans a. The sealing 3 oftheir tips to the inner surface of one of the upper package 1 and lowerpackage 2 prevents recoiling of the condom body A immediately after thepackage C is opened, avoids forming an excess extension part in thefitting tapes B, and makes it possible to fit the body A appropriatelyon the glans without directly touching it with the fingers, i.e., a “notouch” fitting is possible.

The length of this extension part 5 is chosen within a suitable rangesuch that, after opening the package C, subject to the condition thatthe condom body A has been fully exposed from the split package piecesC′, the condom body A does not recoil. To prevent the fitting tape Bfrom being excessively drawn out after opening the package C, its lengthis a length such that the tear ends of the package pieces C′ areexternal tangents to the condom body A )when the condom body A is fittedon the glans in intimate contact therewith, as shown in FIG. 14 and FIG.15. Its minimum required length is given by the following equations (1),(2) (FIG. 17).

When the seal part 3 is situated further inside than the outercircumference of the condom body A, equation (1) is used, and when it issituated further outside, equation (2) is used.

E=r+πr+R−x  (1)

E=r+πr+R+x  (2)

where

R=radius of external diameter of condom body A

r=radius of rolled part of condom body A in which fitting tape B is alsorolled

x=distance from outer circumference of condom body A to seal part 3

E=length of extension part 5

The above equations (1), (2) refer to the case where the seal 3 is tothe upper package material 1 in a center split, and when the seal part 3is sealed to the lower package material 2 or when it is unequallydivided to the left and right, the length may also be calculated basedon them.

The distance x from the outer circumference of the condom body A to theseal part 3 is basically arbitrary, but if a value of x is used wherethe following inequality (3) is satisfied, the condom body A is exposedfrom the package C and pulled out further, which is undesirable.

r+πr+R−x<{square root over ((x−r)²+(2r)²)}  (3)

The length of the extension part 5 at this time is given by thefollowing equation (4):

E={square root over ((x−r)²+(2r)²)}  (4)

The extension part 5 becomes longer the nearer the seal part 3approaches to the rim c of the package C outside the outer circumferenceof the condom body A, and as excess slack may be trapped in the seal(thermocompression bond) of the rim, the distance x from the outercircumference of the condom body A to this seal part 3 must be asuitable magnitude, and preferably small.

The minimum length occurs when the seal part 3 is sealed to the upperpackage material 1 at about ⅔ of a radius toward the center (toward theinside) of the condom body A from the outer circumference of the condombody A, and the length E of the extension part 5 at this time satisfiesthe aforesaid equation (1), which is most preferable.

It is practical to provide the extension part 5 larger than E computedfrom the above equations (1), (2), but if it is made too large, thecondom body A is pulled out too far from the package pieces C′ anddroops after the package is opened, which gives rise to the aboveproblems. It is therefore best not to adhere strictly to the aforesaidequation, and to allow a tolerance of several mm (e.g., −3 mm to +5 mm)in ½ of the external radius R when the condom body A is rolled uptogether with the fitting tape B.

By sealing the end of the extension part 5 determined by the aforesaidmethod in one piece with the inner surface of one of the upper packagematerial 1 or lower package material 2, the extension part 5 can bemaintained at a predetermined length, entry of air to the glans part adue to the unrolling of the condom body A immediately after the packageC is opened can be prevented, drooping of the condom body A due toexcess withdrawal of the fitting tape B can be avoided, and the body Acan be appropriately fitted on the glans. Further, the grip hand andthigh of the user do not interfere with each other.

As described above, this extension part 5 is formed by rolling up thefitting tape B together with the condom body A, dividing the fittingtape B to the left and right for predetermined lengths beyond the coiledpart 4, i.e., on the front surface in the vicinity of the glans or onthe coiled rear surface, and sealing 3 the ends of this divided materialto the inner surface of one of the upper package material 1 or lowerpackage material 2 of the package C. This seal part 3 between thefitting tape B and package C is preferably formed by adhesive orthermocompression bonding at a position removed from the peripheral sealbetween one of the upper package material 1 and lower package material 2and the fitting tape B, which is a position in the vicinity of thecoiled part 4 of the condom body A, prior to sealing 9 the rim c of theupper package material 1 and lower, package material 2. However anextension part of predetermined length can still be maintained even ifthe position of the seal part 3 is the rim c of the package C as in FIG.9, and it may also coincide with the position of the seal part 9 of therim c which is sealed later.

This is because if the seal 9 by thermocompression bonding of the rim cof the upper package material 1 and lower package material 2, and theseal 3 by thermocompression bonding with the fitting tape B, are formedin one operation (simultaneously), the position of the fitting tape Btends to shift, and there tends to be scatter in the length andorientation of the extension part 5, which are not constant. Therefore,the seal 3 between one of the upper package material 1 and lower packagematerial 2 with the fitting tape B beyond the extension part 5 is formedbefore the seal 9 of the rim c between the upper package material 1 andthe lower package material 2. In this way, the length and orientation ofthe extension part 5 of the fitting tape B are more precise, and theextension part 5 can be tightened before fitting without peeling off theseal 3 when the package is opened.

Due to this seal 3, the end of the fitting tape B can be brought up tothe seal 3, and an excess length 6 beyond this may be left as it is orextended to the peripheral part c of the package C, and sealedsimultaneously when the seal 9 of the rim c of the package C is formedbetween the upper and lower package materials 1, 2. Thus, if the excesslength and end of the fitting tape B are gripped between the upperpackage material 1 and lower package material 2 so that the end of thefitting tape B is also firmly sealed in one piece with the packagematerials 1, 2, a product can be obtained which is temporarily sealedeven if the seal 3 is peeled off when the package is opened.

In the package C, the condom body A which is rolled up together with thepair of left and right fitting tapes B is fixed to the upper packagematerial 1 or lower package material 2. To maintain the extension part 5of predetermined length beyond the rolled part of the fitting tape B,after sealing 3 to the inner surface of one of the upper and lowerpackage materials, the other package material is placed over the condombody A so that the condom body A is sandwiched, and then the seal 9 isformed by thermocompression bonding, etc., of the peripheral part c ofthe package materials slightly removed from the condom body A so as toenclose the condom body A. An opening notch 7 such as for example aV-shaped notch or a straight indent is provided in the center part ofthe rim, and plural rows of tear lines 8 for opening ate formedsubstantially in the center, of one or both of the upper and lowerpackage materials.

The package materials 1, 2 comprise films or package materials havingthermocompression bonding properties known in the art in this kind oftechnical field. For example, the upper package material 1 comprises atransparent plastic film and the lower package material 2 comprises analuminum foil package material wherein a sealant is laminated, but thealuminum foil package material 1 may also be an aluminum foil packagematerial wherein a sealant is laminated. Too much opening of the packagecan be prevented, and fitting is assisted, by displaying the position onthe upper package material 1 where the package is to be gripped (held)by both hands, and the left and right thumbs are to be placed when thepackage is opened, or by printing instructions to be used when thepackage is opened. Regarding the position of the thumbs, the tips of theleft and right thumbs, or the left and right thumbs, are displayedsubstantially parallel so that the package C is held by the left andright hands, the notch 7 is gradually opened, and the thenars (or bases)of the left and right thumbs come in contact before the package is tornopen to the end.

The sealant of the upper and lower package materials 1, 2 and thefitting tape B is preferably comprised of a polyolefine having good heatseal properties (polyethylene, random polypropylene or EVA),polyethylene being particularly convenient.

The tear line 8 is generally straight like a “seam”, but rectilinearitymay be conferred by providing a slanting, thin part in the shape of theJapanese letter “ha” or an inverted Japanese letter “ha” in the openingdirection substantially in the center of one or both of the packagematerials on the front and rear surfaces by die pressing or embossing,as shown in the drawings. This tear line, which is used for opening thepackage, is a thin part which is formed in the shape of the Japaneseletter “ha” or an inverted Japanese letter “ha” by applying apredetermined pressure from the front and rear surfaces of the packagematerials 1, 2 in the shape of the Japanese letter “ha” or an invertedJapanese letter “ha”, as described above. By forming plural (e.g. 2-7)rows of the tear lines 8, the package can be opened efficiently withoutany shift in the tear direction (opening direction) along the notch 7 inthe center part of the upper end of the package C even if the startingand finishing points of this opening tear line on the front and rearsurfaces do not perfectly coincide.

This tear line is not limited to the shape of the Japanese letter “ha”or an inverted Japanese letter “ha”. Rectilinearity can be conferred inthe way the package is opened and ease of opening can be enhanced byforming the tear line in a staggered shape as a combination of slantinglines and a straight line, such as for example in the shape of a letter“Y” or an inverted letter “Y”, or a shape wherein a slanting line isslightly shifted up or down so that the extrapolation of one slantingline intersects with the other slanting line.

Industrial Applicability

Next, the method of using the condom according to the invention will bedescribed.

As shown in FIG. 10, the package C is gripped with both hands by placingthe thumbs in the thumb grip positions displayed on the front surface ofthe package C and placing the four fingers of the left and right handson the rear surface, the package is gradually torn open from the notch 7to the end along the tear line 8 with the little fingers of the left andright hands still in place (FIG. 11), the thenars (bases) of the thumbsof both hands come in contact and the contact parts are graduallyseparated (FIG. 12). The parts are completely separated up to the end ofthe package C, the separated package pieces C′ are pulled apart whilethey are still gripped and the extension parts 5 of the fitting tape Bare pulled out so that the condom body A does not roll back. Opening istemporarily stopped in the state shown in FIG. 14, the condom body A isplaced in intimate contact with the glans (FIG. 15), and the packagepieces C′, which are split into two, are pulled toward the base of thepenis. The fitting tape B and condom body A are then rolled back (FIG.16) so that it is completely fitted over the penis with the fitting tapeB peeled away from the condom body A.
